The course image ontains masspy.
A new version of the image is built whenever the repository is updated. The tag of the build is the same as the branch.
First, determine on the tag to use. It's recommended to use the current quarter. The tag would be "sp23" for spring 2023.
Open the Releases page and click the Create a new release
button. Enter the tag in the "Choose a Tag" field and press enter to confirm. Then click "Publish Release" to create the tag.
You can also create a release using the git CLI.
git tag sp23
git push origin sp23
Re-releasing is the same as making a release, except that we need to delete the existing release.
Open the Releases page, click the Releases tab, and delete the release.
Open the Releases page, click the Tags tab, and delete the tag.
And for CLI users
git -d sp23
git push ---delete origin sp23
Now that the tag and release are gone, follow the "How to create a release" instructions.
